I see this inconsistently in the current R-devel and R-patched. It's easiest to see with history turned on. For example,

x <- rnorm(100)
y <- rnorm(100)
plot(x,y)
# make sure history recording is turned on

identify(x,y,1:100)
# Mark a few points, then stop

plot(y, x)
identify(y,x,1:100)
# Mark some more points

# Now hit PgUp to go to the previous page: sometimes the identifiers show up, sometimes not. Hitting PgDn sometimes loses the latest ones.

I haven't spotted what the pattern is in what causes the losses yet. Mihai, can you put together a recipe that *always* loses the identifiers?
